Abstract

Abstract A cage for mounting a pluggable fiber optic transceiver onto a host circuit board. The cage is entirely formed from a single blank, which is folded along predefined fold lines to form top, bottom, and side walls that are secured by a latch. A series of semi-resilient feet extend downward from the cage and are pressed into corresponding plated holes provided in the host circuit board such that the cage is secured to the circuit board without soldering. The feet are integrally formed on the blank during the blank stamping process such that they extend perpendicular to the bottom wall after the folding process. Each foot is has an elongated oval outer edge and defines an eye-shaped opening that facilitates resilient deformation when pressed into the plated holes of the host circuit board.
